In a Dutch oven or large pot, saute green pepper, onion, garlic and butter until tender. Add vegetables, water, bouillon, salt and pepper; bring to a boil. Reduce heat; cover and simmer for 20 minutes or until the vegetables are tender. Combine flour and milk until smooth; stir into pan. Allow to thicken at a low temperature. Add the parsley and other spices. Just before serving, stir in the cheese until melted.
